To all whom it may concern:

Be it known that I, lVILLIAM R. MOHILL, a citizen of the United States, residing at Moran, in the county of Allen and State of Kansas, have invented a new and useful Oil-Burner, of which 'the following is a specification.

The device forming the subject matter of this application is a burner adapted to handle crude oil and like fuels, and the invention aims to provide, in a device of the kind specified, novel means whereby .a thorough mixture of oil and gas willbe brought about. Another object of the invention is to provide novel means whereby the fuel will be thoroughly vaporized.

A further object of the invention is to provide novel means whereby the flame will be protected from drafts. The invention aims to provide a structure of the kind mentioned which will burn clean, and give a hot blue flame, with a minimum expenditure of fuel.

It is within the province of the disclosure to improve generally and to enhance the untility of devices of that type to which the present invention appertains.

lVith the above and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, Within the scope of what is claimed, changes in' the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in vertical section, a device constructed in accordance with the invention; Fig. 2 is a fraginental top plan of the pan; Big. 3 is a fragmental top. plan of the air battle.

The device forming the subject matter of this application includes an annular pan 6 which may be supported in any suitable way in a stove, furnace or other container. The pan 6 comprises a bottom 40, an upstanding marginal flange 41 and a central tube 42, across which extends a cross bar 17, including a hub 19. Openings 18 exist on each side of the cross bar 17. The tube 42, the flange 41 and the bottom 40 of the pan form an annular trough 43. A wick 7. preferably made of asbestos, is located in the trough 43 and surrounds the central tube 42 closely.

Specification of Letters Patent.

Application filed April 28, 1918. Serial No. 230,304.

Disposed below the pan 6 is a baffle plate 5 having a circumscribing rim 28 and provided with upstanding lugs 23 attached to the bottom 40 of the pan 6 by means of securing devices 16. A fuel supply conduit is provided, the same including a pipe 4 passing through the battle plate 5, and

through the hub 19.0f the cross bar 17 By means of an elbow 3, the pipe 4 is connected to a pipe 2 carrying a valve 1 to which the fuel is supplied, preferably under pressure. The particular arrangement-of piping used will depend, of course, on the nature of the structure wherewith the device forming the iubject matter of this application is-assemled.

The invention comprises a lower spreader internal collar 15 receiving the upper end of the pipe 12, the dome bein supported removably on the upper end of t e pipe.

The dome 10 has an upstandingcar 73 provided with an opening 30, adapted to receive a hook or the like, whereby the dome 10 may be lifted off the upper end of the pipe 12 at any time, to permit a cleaning of the device. The lower edge of the dome 1O lies slightly below the upper surface of the lower spreader plate 8. A vaporizing tube 11 surrounds the pipe 12 and is spaced therefrom as shown at 27, the upper end of the vaporizing tube being threaded into the col lar 15 of the dome 10. The lowerjend of the vaporizing tube 11 is threaded into a boss 20, constituting a part of an upper spreader plate 9, disposed above the lower spreader plate 8, the spreader plates being separated slightly, as shown at 26. I

In practical operation, the valve 1 is opened and the fuel passes through the con duit which comprises the pipes 2, 4 and 12 and flows through the notches 14 into the space 27 between the pipe 12 and the vaporizing tube 11. Thence the oil flows, through the space 26 between the spreader plates 8 and 9 and thence onto the wick 7. In this connection it.is to be observed that the lip 29 on the plate 8 serves to prevent the oil from running backwardly along the under surface of the plate, and serves, also, to direct the oil downwardly onto the wickT. The valve 1 is then closed, and the oil on the wick 7- is ignited, the spreader plates 8 and 9 being heated and the vaporizing tube 11 being heated, so that the oil as it flows downwardly in the space 27 between the tube 11 and the pipe 12, will be converted into gas. The valve 1 may then be opened to secure the desired feed of oil, and to regulate the flame which, of course, burns at the peripheries of the plates 8 and 9. The air passes upwardly through the openings 18 on each side of the cross bar 17 and facilitates combustion, it being noted that the baiiie plate 5 serves to direct the air beneath the pan 6, and to hold the air beneath the pan, to some extent, so that the air is heated before it passes upwardly through the openings 18. The dome 10 extends downwardly below the space 26 between the spreader plates 8 and 9, and, consequently, the flame is shielded from the wind and the air and is confined within the dome, so as to promote the com bustion.

Excess oil, at the starting of the device, will he received and held in the trough 43, and should any excess oil find its way downwardly onto the baflie plate 5, the oil will be retained by the rim 28 of the bafile plate.

and will ignite after a short time, thereby heating up the device and aiding in securing a proper vaporization of the' oil, as the same flows downwardly between the vaporizing tube 11 and the pipe 12, and between the spreader plates 8 and 9. As hereinbefore explained, the dome 10 may be lifted oif the pipe 12 at any time, carrying with it the tube 11 and the spreader plate 5), the device thus being opened up for cleaning or repairs.

Having thus described the invention, what is claimed is 1. In a device of the class described, a fuel supply conduit; a dome supported re inovably by the upper end of the conduit; a vaporizing tube carried by the dome and surrounding a portion of the conduit, the vaporizing tube and said portion of the conduit being spaced apart; a spreader carried by the lower end of the vaporizing tube; and a second spreader spaced from the first spreader and'cooperating therewith, the second spreader being carried by the conduit.

2. In a device of the class described, a pan having a central opening; a bafiie disposed below the pan; a fuel supply conduit passing upwardly through the baflie and through the pan; a first spreader plate carried by the conduit and disposed above the opening; a vaporizing tube surrounding the conduit above the spreader plate; means for establishing communication between the upper ends of the conduit and the vaporizing tube; and a spreader plate carried by the lower end of the vaporizing tube and disposed above the first spreader plate.

In a device of the class described, a pan having a tube; a wick carried by the pan and. surrounding the tube; a fuel supply conduit passing upwardly through the tube; a first spreader plate mounted on the conduit and disposed above the tube, the spreader plate having a depending flange located above the wick; a vaporizing tube surrounding the conduit above the spreader plate; means for establishing communication between the upper ends of conduit and the vaporizing tube; and a second spreader plate carried by a vaporizing tube and disposed above the :l'irst spreader plate.

41. In a device of the class described, a pan having an opening; a bafiie disposed below the pan; a fuel supply conduit extended upwardly through the battle and the pan; a first spreader plate carried by the conduit, the pan having an opening located below the spreader plate; a dome supported remov'ably on the upper end of the conduit; a vaporizing tube carried by the dome and surrounding a portion of the conduit; and a second spreader plate mounted on the vaporizing tube and located above the first specified spreader plate.

In testimony that I claim the foregoing as my own, I have hereto atlixed by signature in the presence of two witnesses.
